Before leaving Chen Gan's place, Luo Yu spent about fifteen minutes making an energy wing, and all the process was completed in the spiritual space.

Many nine-leaf ice flower crystals float in the air, forming a hanging "Milky Way", shining with brilliance, really like the stars in the sky, like the most beautiful works of art in the world.

The energy crystallization of one plant is not enough to form a complete energy wing, it takes at least four plants to form the strength equivalent to the flame energy wings, Luo Yu uses the same production method, in the spiritual space, close to the edge of the wooden boat, leaning over and holding a few "river water" in his hand, these "river water" do not fall after leaving the water, but float in the air, as if they are completely unaffected by gravity, and in other words, this is a spiritual space, and there does not seem to be the concept of "gravity".

According to his memory, Luo Yu successfully condensed together on the energy crystallization of these four flowers, and finished carving the winged runes, and through the strokes of the runes, the four nine-leaf ice flowers were tightly connected, connecting together from the root system, forming a magnificent pattern, the leaves were crystal clear, and there was a trace of cold steaming up.

When sketching these runes in the spiritual space, Luo Yu was also able to take into account the things in reality, as long as he separated a little mind, he could complete many actions in the mental space, and when a well-made energy wing prototype appeared in Luo Yu's hand, Chen Yan was surprised.

"When did you finish?" Chen Yan looked at Luo Yu with a surprised expression, just now he saw Luo Yu drinking coffee there alone, silent, and didn't see how he completed this action.

But he was soon drawn to the almost art-like thing in front of him.

A total of thirty-six leaves spread out from a central point, with golden rune lines flowing on them, gold and white complementing each other.

Luo Yu was also observing these golden runes, they were carved on them by Luo Yu, and then it began to flow and extend, forming new and deeper patterns, and it itself was also constantly growing, constantly improving this set of circuits.

"It's amazing...... Able to grow and improve the scientific and technological system independently...... This is ......" Chen Gen was completely attracted to it, and began to study it as if no one else had it.

Luo Yu didn't bother, he patted Liang Hao's shoulder and motioned for him to go downstairs with him.

Even if Luo Yu knew how the runes were depicted, he couldn't teach people to copy them, after all, the most important material - the mysterious "river water" in the spiritual space, could only be used by Luo Yu.

What kind of substance is that, Luo Yu doesn't know, among the memory fragments he got at the beginning, he only thinks that it should be a very advanced energy form.

Walking downstairs, Luo Yu planned to discuss this matter with Ling Lin, since he had obtained the energy crystal, he had to use it where it was needed most.

"The battleship set sail after about nine o'clock in the evening, and you really plan to go to such a dangerous place?" Luo Yu looked at Liang Hao, who had been following behind him, and asked casually.

Liang Hao nodded and said seriously: "Yes, I have a reason why I have to go!" ”

……

Luo Yu didn't ask, the two separated at a fork in the road, and Luo Yu went to stop at the airport.

Ling Lin was still busy there, it was the hot season, and it was the noon sun, hanging high above her head, such an environment was really hard to work outdoors for a long time.

"Ling Lin!" Luo Yu shouted in the distance, she lifted the floor and wiped the sweat from her forehead, pulled her hair, and looked up.

Luo Yu smiled and came over with a lunch box, stretched out the box in front of Ling Lin, and said, "Let's rest first, eat something!" ”

"Thank you!" Ling Lin also took it with a smile, but then put the lunch box on the table next to him, and then looked at Luo Yu and said, "I'll eat later, everyone else is busy at this time, I can't be idle alone, and the time is urgent, I'm worried about the safety of the front line......"

The perennial military career has allowed Ling Lin to develop the spirit of enduring hardships, and she is not as weak as a girl of this age, and her image in front of people is always energetic and capable.

"I can't afford to lose much time...... And I have something important to tell you. Luo Yu handed the lunch box to Ling Lin again.

Ling Lin glared at Luo Yu lightly, paused on his face for two or three seconds, Luo Yu was a little nervous when he looked at it, but fortunately, Ling Lin immediately smiled, took the lunch box, and walked to the chair to the side and sat down.

"Sit down, too!" She patted the chair next to her.

……

"Seriously?" At first, Ling Lin was still pulling the lunch box, while listening to Luo Yu a little casually, it seemed that she was indeed very hungry, if it wasn't for Luo Yu watching from the side, she would almost gobble it up.

However, when she heard that she could mass-produce energy wings, she looked at the other party in disbelief.

She knew that Luo Yu had a pair of flame energy wings, which were composed of precious elemental spirit energy crystals, and there was no way to produce this kind of material, because it came from another time and space, and the scientific research community had conjectures about this kind of energy crystallization, and the ability core could absorb energy from another space, but it could not absorb this kind of solid materialized energy body.

At present, Huaxia is still in the research stage when the human body enters another space, and there are no examples that can make people travel safely to and from another space. As for some forces in the West, they may already have mature technology for this kind of technology.

"Well, that's it." Luo Yu demonstrated to Ling Lin on the spot, four energy bodies appeared in his hands, and streams of water appeared on his fingertips, carving strange symbols on the energy bodies, and when the last stroke was completed, these runes burst out with golden brilliance together.

The golden light shone brightly, and a prototype of an energy wing was formed, and in less than 10 minutes before and after, it was obvious that Luo Yu's proficiency had improved a lot.

"This kind of energy wing does not need the supply of energy, it can independently absorb the energy in the other space, so that the warrior can take off and fight without the help of mechas." Luo Yu explained.

"This is really a valuable weapon!" Ling Lin held the crystal in his hand and couldn't help but admire, his eyes glowing with excitement.

You must know that the current set of mechas, even if they are ordinary goods, is also an expensive luxury, it is impossible for every soldier to have a pair, and the mecha equipped with flying ability consumes a huge amount, and the supply and supply of energy is also a troublesome thing, only people with the core of ability can fully control this kind of mecha and can replenish it in time.

However, the proportion of humans who open the genetic lock is only 1/10,000, and even fewer can form the core of the ability.

"Put it on for me!" Ling Lin couldn't put down the energy body composed of the Nine Leaf Ice Flower in his hand.
